Quick answer: No — dental chews alone are not enough to keep your dog’s teeth and gums healthy. They’re a helpful supplement to a dental routine, and the good ones can measurably reduce plaque and tartar, but they don’t reach below the gumline or replace brushing and professional cleanings. Think of chews as one tool in a kit, not the whole kit. Below, we’ll break down what they actually do, what the research shows, and how to build a routine that actually protects your dog’s mouth.

What Dental Chews Actually Do (and Don’t Do)
Dental chews work through two main mechanisms: mechanical abrasion and, in some cases, chemical action.
When your dog gnaws on a chew, the friction scrapes soft plaque off the tooth surface before it hardens into tartar. Some chews are also coated or infused with active ingredients — like sodium hexametaphosphate, delmopinol, or zinc — that interfere with plaque bacteria or slow mineralization.
Here’s what a quality dental chew can do:
– Reduce plaque accumulation on the crown (the visible part of the tooth)
– Slow tartar buildup, especially on the large chewing teeth in the back
– Freshen breath (usually a symptom of reduced bacterial load)
– Provide safe, satisfying chewing enrichment
And here’s what a dental chew cannot do:
– Clean below the gumline. This is where periodontal disease actually starts, and chews simply don’t reach it.
– Remove existing tartar. Once plaque hardens into calculus, only a scaler — used during a professional cleaning — removes it.
– Reach the front teeth and inner surfaces well. Most chewing happens on the back molars and premolars, so incisors and the tongue-side of teeth get little benefit.
> Vet insight: Over 80% of dogs show signs of periodontal disease by age three. The disease process is driven by bacteria under the gumline — exactly where chews can’t go. That’s the single most important reason chews can’t stand alone.

Are Dental Chews Enough on Their Own?
Short version: no.
A dental chew is a bit like chewing gum for humans. Sugar-free gum can help reduce cavities and freshen breath, but no dentist would tell you to skip brushing and cleanings because you chew gum. The same logic applies to your dog.
The problem is coverage and depth. Even the best chew only addresses roughly the parts of the tooth the dog actively grinds on, and only above the gumline. Periodontal disease — the leading dental problem in dogs — begins in the gingival pocket, progresses to bone loss, and can ultimately cause tooth loss and systemic inflammation affecting the heart, liver, and kidneys.
So chews are genuinely useful — studies show effective ones cut plaque and tartar meaningfully — but “reduces plaque by a third” is not the same as “prevents dental disease.” You need a routine that also disrupts bacteria below the gumline (brushing) and removes what accumulates anyway (professional cleaning).
Bottom line: Dental chews are a strong supporting player. They are not a substitute for brushing or veterinary dental care.

What the Research Says About Dental Chews
You don’t have to take marketing claims at face value. The Veterinary Oral Health Council (VOHC)&tag=pulseprotocol-20) independently reviews dental products and awards a seal to those that meet a threshold for reducing plaque or tartar in controlled trials. When a product carries the VOHC Seal of Acceptance, it means the plaque/tartar reduction claim has actually been tested — not just asserted on the bag.
Key takeaways from the body of research:
– Effective chews reduce tartar substantially. Multiple controlled studies on VOHC-accepted chews show meaningful reductions in calculus accumulation versus dogs eating dry food alone.
– Daily use matters. The benefit comes from consistent mechanical action. A chew twice a week does far less than a chew every day.
– Texture and time-to-consume matter. Chews that take longer to eat and require real gnawing outperform chews a dog crunches in ten seconds.
– Chews don’t reverse existing disease. Every credible study measures prevention of new buildup — none show chews removing established tartar or healing gum disease.
The practical implication: look for the VOHC seal, use the chew daily, and understand you’re buying slower buildup, not a cleaning.

Key Features to Look for in an Effective Dental Chew
Not all chews are created equal. Here’s what separates a genuinely effective chew from a glorified treat:
1. VOHC Seal of Acceptance
The single most reliable quality signal. It means the plaque or tartar claim was independently verified.
2. Appropriate Size and Firmness
The chew should be sized for your dog’s weight (brands offer XS–XL ranges) and firm enough to require real chewing — but not so hard it risks fracturing a tooth. A good rule: if you can’t make a slight indent with your thumbnail, it may be too hard.
3. Time-to-Consume
A chew your dog demolishes in seconds provides almost no mechanical benefit. You want something that takes a few minutes of genuine gnawing.
4. Digestibility
Look for chews that break down easily in the digestive tract, which lowers the risk of blockages — especially important for gulpers.
5. Sensible Ingredients & Calories
Every chew adds calories. Check the count and adjust meals accordingly, especially for small breeds. Avoid excessive fillers and added sugars.
6. Active Anti-Plaque Ingredients (Bonus)
Ingredients like sodium hexametaphosphate or delmopinol add a chemical layer of plaque control on top of the mechanical scrubbing.

Dental Chews vs. Brushing, Water Additives & Dental Diets
Chews are one option among several. Here’s how they stack up against the other common tools — and why the best answer is usually “several of these together.”
| Method | Reaches Below Gumline? | Effort | Effectiveness |
| Brushing (e.g. Virbac C.E.T. Enzymatic Toothpaste) | Partially, at the gumline | High (daily) | Gold standard for home care |
| Dental Chews | No | Very low | Good supplement |
| Water Additives | No | Very low | Mild, convenient |
| Dental Diets (e.g. Hill’s Prescription Diet t/d) | No | Low | Good for tartar control |
| Professional Cleaning | Yes (full cleaning) | Vet visit | Essential baseline |
Brushing is the closest thing to the human standard of care because it physically disrupts plaque right at the gumline — the one spot chews miss. Daily is ideal; even three times a week helps. Use a dog-specific enzymatic toothpaste like Virbac C.E.T. Enzymatic Toothpaste — never human toothpaste, which contains ingredients toxic to dogs.
Water additives are the low-effort option: you add them to the water bowl to help control bacteria. Convenient, but mild — best as a bonus, not a backbone.
Dental diets like Hill’s Prescription Diet t/d use special kibble that scrubs the tooth as the dog bites through it instead of shattering. For tartar-prone dogs, a VOHC-accepted dental diet can do real work.
None of these reach below the gumline the way a professional cleaning does — which is why that stays on the list no matter what else you do.

Best Types of Dental Chews by Dog Size and Age
Matching the chew to the dog matters as much as the brand.
Small & Toy Breeds
Small dogs are especially prone to dental disease due to crowded teeth. Choose a chew sized specifically for small mouths — Greenies Teenie or the smallest Whimzees, for example — and watch calories closely, since a single large chew can be a big chunk of a toy breed’s daily intake.
Medium & Large Breeds
Bigger dogs need bigger chews, both for effective scrubbing and for safety (small chews are a choking hazard for large dogs). Size up within the same product line rather than switching brands.
Puppies
Wait until adult teeth are in and chewing is well established — generally around six months — before using firm dental chews. For younger puppies, softer, puppy-specific options and finger-brush training are more appropriate. Always check the label’s age guidance.
Senior Dogs
Older dogs often have worn or fragile teeth, and firm chews can risk fractures. Opt for softer, more pliable chews like Whimzees in an appropriate size, and talk to your vet — a senior with existing dental disease may need a cleaning before any chew will help.
Power Chewers
Dogs that destroy everything need durable, digestible chews sized generously. Avoid anything so hard it could crack a tooth (a common cause of painful fractures), and always supervise.

Building a Complete Dog Dental Care Routine
Here’s what an actually effective, chews-included routine looks like:
1. Brush daily (or as often as you can). This is the foundation. Use an enzymatic dog toothpaste like Virbac C.E.T. Enzymatic Toothpaste and build the habit gradually with positive reinforcement.
2. Give a VOHC-accepted dental chew every day. Pick one sized for your dog — Greenies, VeggieDent, or DentaLife — and count it toward daily calories.
3. Consider a dental diet or water additive as an easy extra layer, especially for tartar-prone dogs.
4. Get annual (or semi-annual) professional cleanings. This is the only step that cleans below the gumline. Your vet can also catch problems — fractured teeth, resorptive lesions — you’d never see at home.
5. Check the mouth weekly. Lift the lip and look for red gums, brown tartar, broken teeth, or bad breath. Early problems are cheaper and less painful to fix.
Consistency beats intensity. A modest routine done every day protects teeth far better than an elaborate one done occasionally.

Our Verdict
Dental chews are worth using — but they are not enough on their own.
The evidence is clear: a good, VOHC-accepted dental chew given daily meaningfully slows plaque and tartar buildup. That’s a real, measurable benefit, and there’s no reason to skip it. But chews can’t reach below the gumline, can’t remove hardened tartar, and can’t reverse existing disease — which is exactly where the serious dental problems live.
So treat chews as one layer of a complete routine, not the whole thing:
– Best all-around chew: Greenies Original Dental Chews — proven, palatable, and available in every size.
– Best for sensitive stomachs / vet-recommended: Virbac C.E.T. VeggieDent FR3SH.
– Best value for daily use: Purina DentaLife Daily Oral Care.
– Best natural option: Whimzees by Wellness.
– Don’t skip this: pair any chew with Virbac C.E.T. Enzymatic Toothpaste and an annual professional cleaning.
Buy the chew your dog will actually chew every day — but pair it with brushing and regular vet cleanings. That combination, not any single product, is what keeps a dog’s mouth healthy for life.
